AB We present model equations for the trapping and accumulation of particles in a cylindrical channel withnanostructured inner walls when a fluid passes through, carrying a moderate load of impurities. The basic ingredientof the model is the introduction of a phenomenological ‘effective-charge density’ of the walls, related to the electricalcharges exposed in the nanotexture. The effective charge is gradually reduced as the flow runs through the channeland the trapped impurities cover the internal walls. Based on the proposed equations, the position and timedependence of the areal density of trapped impurities, and the filtration performance, may be calculated. It isproposed that experimentally testing these results may help to understand the enhanced trapping capabilityobserved in many diverse nanotextured channel structures.
